Samsung 830 SATA3 SSD 256GB Review
Using the graphing feature of AIDA64 to test the ability of the controller, cache and NAND itself to deliver consistent results we think it's fair to say that in Linear testing they are unbelievable consistent. Even by SSD standards this is a very flat Read graph.
Writing is even more consistent. Normally there are some dips as the controller switches between each memory chip, but with such a huge amount of cache onboard, and utilising nothing but Samsung products, the 830 is as flat as a pancake and as smooth as the butter you'd pour over them.
